Which full-cycle B2B sales outsourcing agency should you choose?

There is no single best provider for every B2B company. NxLead is designed for SaaS companies, agencies and specialised service businesses seeking a coordinated outbound operation across cold email, LinkedIn, calling, qualification, sales conversations and follow-up. Martal and Aexus are established options for B2B technology companies expanding across international markets. Sales Focus, Acquirent and MarketStar may suit organisations that need larger or more traditional outsourced sales teams. The right choice depends on company size, sales complexity, target market, required channels and whether the provider must support closing rather than only appointment setting.

How We Evaluated the Agencies

Inclusion in this comparison is based on the following criteria, evaluated using each provider’s official website:

iQor was considered but excluded because its official website describes customer experience BPO and inbound customer service operations; there was no evidence of B2B prospecting, SDR or new business development outsourcing for external companies at the time of review.

Important: This is not a ranking based on performance data. The comparison evaluates publicly described services and client fit. Actual performance depends on the offer, target market, sales cycle length, provider team and implementation. Request references and relevant case studies from any provider before committing.

Martal Group

Martal Group is a North American B2B sales outsourcing and lead generation agency founded in 2009.

It reports working across 50+ B2B verticals with more than 2,000 companies.

How to Choose a Full-Cycle B2B Sales Agency

Use the following framework before selecting a provider:

  1. Determine which sales stages need outsourcing. Define whether you need prospecting only, appointment setting only, or coverage through to closing. Document this clearly before requesting proposals.
  2. Confirm who conducts discovery calls. Ask whether discovery is handled by the provider’s team or handed back to your internal account executives after the first meeting.
  3. Ask who owns follow-up. Persistent follow-up after initial outreach is often where deals are won or lost. Confirm the provider’s follow-up model and ownership.
  4. Confirm whether the provider supports proposals and negotiation. Some providers stop at booking a meeting; others continue through proposal coordination and objection handling.
  5. Define contractual approval authority. Even when a provider conducts sales conversations, the client typically retains authority to approve final pricing and contract terms. Confirm how this is handled.
  6. Verify channel capability. If your buyers respond primarily to LinkedIn or cold email, confirm the provider actively uses those channels rather than relying solely on phone.
  7. Review relevant case studies. Ask for case studies in your industry, with similar average contract values and comparable sales cycles. Distinguish between meetings booked and deals closed.
  8. Agree on qualification criteria. Define what a qualified lead or meeting means to your business before the engagement starts.
  9. Confirm CRM visibility. Ask who owns the data, which CRM is used, what reporting is provided and how frequently.
  10. Understand pricing and commission structure. Clarify retainer, commission, hybrid models and what happens if targets are not reached.
  11. Use a defined pilot period. Start with a time-limited pilot with agreed performance criteria before committing to a long-term engagement.

Questions to Ask Before Hiring an Outsourced Sales Team

Full-Cycle B2B Sales Outsourcing FAQs

What is full-cycle B2B sales outsourcing?

Full-cycle B2B sales outsourcing means delegating the entire outbound sales process to an external provider — from identifying and researching prospects through outreach, qualification, follow-up, sales conversations and closing support. It differs from lead generation or appointment setting services, which deliver prospects or booked meetings but leave sales conversations and deal closure to the client’s internal team.

What is the difference between appointment setting and full-cycle sales outsourcing?

Appointment setting services identify prospects, conduct outreach and book meetings on behalf of the client. The client’s internal team then conducts the sales conversation and manages the deal. Full-cycle sales outsourcing extends the provider’s involvement through qualification, discovery calls, follow-up, objection handling, proposal coordination and, in some engagements, deal progression through to a decision. The client retains final contractual authority unless otherwise agreed in writing.

Can an outsourced sales agency close deals?

Some providers explicitly offer closing support; others do not. Among the providers in this comparison, Martal Group (full-cycle tier), Aexus, Acquirent and NxLead describe closing support or full-cycle engagement on their official service pages. Sales Focus and MarketStar describe deal execution capability depending on engagement type. Whether closing is included depends on the specific contract. Confirm this in writing before signing any agreement.

How much does B2B sales outsourcing cost?

None of the providers in this comparison publish standard pricing. Costs vary by scope, team size, channels, markets and engagement duration. Retainer-based, commission-based and hybrid models all exist in this market. Request a scoped proposal from each provider based on your specific requirements, and compare the total cost against your expected contract value and sales cycle length.

Is outsourced sales suitable for SaaS companies?

Yes, provided the provider has relevant B2B SaaS experience and understands SaaS qualification criteria, typical sales cycle lengths and product positioning requirements. NxLead specifically describes SaaS companies as a primary client type and publishes case studies from SaaS and technology businesses. Martal Group also lists SaaS among its target verticals. Ask any provider for case studies with similar average contract values, deal complexity and sales cycles before committing.

How long does an outsourced sales programme take to produce results?

Timeline varies significantly by market, offer, sales cycle length and which stages are outsourced. Early outreach responses may appear within weeks of campaign launch; qualified leads typically take four to eight weeks from launch depending on targeting precision and response rates; closed deals depend entirely on the client’s sales cycle, which may range from days to many months. Request realistic timeline expectations specific to your industry, average deal size and target buyer from any provider before committing.

Should companies outsource the entire sales cycle?

Not always. Many B2B companies outsource prospecting and qualification while keeping discovery calls and closing internal — particularly where the sale requires deep product knowledge or senior relationship management. Others outsource the full function when they lack internal sales capacity. The decision depends on deal complexity, available internal resources and whether the outsourced provider has demonstrable experience with comparable offers. A defined pilot period with clear handoff criteria between the outsourced team and internal stakeholders is advisable before committing to full-cycle outsourcing.

What should be included in an outsourced sales agreement?

An agreement should specify: which sales stages are covered; who conducts each type of conversation; qualification criteria; data ownership (contacts, outreach domains, CRM records); reporting format and frequency; what constitutes a qualified lead or meeting; whether closing support is included and how it is defined; commission or bonus structures if applicable; notice period and exit conditions; and IP ownership for messaging and sequences developed during the engagement.
